Abstract
It has been found that in the analysis of multi-component mixtures of s-triazines on packed columns some problems arise in that on non-polar stationary liquids (OV-101, SE-30) many peaks of s-triazines overlap and some peaks are not symmetrical, depending on the support material. Separations on a polar phase (Carbowax 20M) were better, but still inadequate.A complex mixture of chloro-, methoxy- and methylthio-s-triazines was separated successfully on high resolution glass capillary columns coated with Carbowax 20M. The optimal temperature for the analysis of s-triazines was determined from the dependence or log R, on 1/T. For the characterization of s-triazins in environmental samples, Kováts retention indices were measured on glass capillary columns with dynamically coated non-polar (OV-101) and polar (Carbowax 20M) stationary liquids. The relationship between the structures of the s-triazines and their retention data was studied.
